Ok. Can't see any options in mris_smooth info reducing the number of vertices.
How would I do that?

Yes, give it both --sval-xyz and --tval-xyz to indicate that the output
is a surface. We usually use mris_smooth to smooth
surfaces; I'm not sure whether this use of mri_surf2surf will work
properly.

Hi John
Doug can say for sure, but I think you want to give it the switch
--sval-xyz so it knows to expect a surface not a
scalar field over the surface.

Thanks guys.
When I run mri_info on the .mgz file I was using before it
seems crash
(nothing happens, and have to press ctrl+c to get the console
back). So I
suppose that partially explains mri_surf2surf not working.
Not sure what's
going wrong there - the command I used was
mris_convert
/work/imaging5/Freesurfer/CBU070282/surf/lh.pial
/home/jdg45/lh.pial_converted.mgz
For the original question - I was using a converted .mgz file
because when I
just give it the path to the 'lh.pial' file in the same
directory it says it
cant determine the file type -
mri_surf2surf --cortex --fwhm 5.0000 --hemi lh --sval
/work/imaging5/Freesurfer/CBU070282/surf/lh.pial --tval
/home/jdg45/CBU070282_smoother_surf.mgz --s CBU070282
Standard output:
ERROR: could not determine type of
/work/imaging5/Freesurfer/CBU070282/surf/lh.pial
Standard error:
Is there a .xxx suffix for those files I should be using?
Incidentally, the reason I'm doing this is that I want to
downsample a
surface file; someone suggested to me to use mri_surf2surf
with the
'trgicoorder' flag. Is this a good way to downsample a
surface?
Thanks,
john

surf2surf actually takes surface overlays (not surfaces
themselves) as input, and they can be in any format that
FS
reads. The wiki is probably not up-to-date as those
options are
ok.

Hi John,
It seems weird that you are using .mgz files (this
suffix is for
volume files) with mri_surf2surf (whose inputs
should be surfaces).
Also, it seems that several of the options you are
trying I don't
believe exist at least according to the wiki (e.g.
-cortex -fwhm). Are
you sure you are using the right command?
